CARBURETER.

SPECIFICATION forming part of Letters Patent No. 696,457, dated April l, 1902..

Application filed April 27, 1901- Serial No. 57,751, (No model.)

To all when?, it may concern:

Be it known that we, OSCAR A. LANE and HUDSON A.DAvENPoRT,oitizens ofthe United States, residing at Adrian, in the county of Lenawee and State of Michigan, have invented certain new and useful Improvements in Carbureters, of which the following is a specication, reference being accompanying drawings.

ro The invention relates to gas-generators of that type. in which the gas is produced by the mixture of a suitable quantity of hydrocarbon oil with air.

The invention consists in the peculiar conx5 struction of generator, and more particularly to the means employed for generating the initial heat for starting said generator into operation, and, further, in the peculiar construction, arrangement, and combination of zo parts, as more fully'hereinafter described,

and specifically set forth in the claims.

In the drawings, Figure l shows the generator in sectional elevation, together with a diagrammatic illustration of the hydrocarbon-tank and connections. Fig. 2 is a perspective view of a portion of the generator.

A is the hydrocarbon-tank, of anysuitable construction, which is provided with means, such as the valve-controlled nipple A', for

3o admitting a quantity of air under pressure in the upper portion thereof above the level of the liquid. This air under pressure serves to feed the oil from the tank and is also used in starting the generator, as hereinafter de- 3 5 scribed.

B is an oil-outlet pipe extending downward within the tank to near the bottom thereof, and C is a pipe connecting with the tank above the level of the liqui 4o D is a casing, preferably of cylindrical form and provided at its lower end with a nipple E, connected with the pipe F. The latter constitutes a vapor-mixing tube, which at its lower end is connected with a tting G and at an intermediate point is provided with a series of air-inlet apertures a. The pipe Fis surrounded by a correspondingly-apertured sleeve H, constituting a valve for restricting said air-inlet aperture a., and connected to 5o this sleeve is a hood I). The fitting G is prohad therein to the vided with a jet-nozzle c, which is directed upwardly and centrally of the pipe F. This nozzle is connected with the pipe C, leading from the upper portion of the hydrocarbontank, and a valve I is connected into the said pipe, preferably just below the nozzle c.

The casing D is open at its upper end and below the opening is provided with a horizontally-arranged perforated diaphragm J.

K and K' are two lugs or ears, preferably 6o formed integral with the casing D an-d projecting upwardly therefrom at diametrically opposite points. These ears serve to support the retort L, which latter is preferably in the form of a hollow disk extending across the opening in the casing D and slightly above the latter. l

tl and d are lugs extending outward from the disk and adapted to fit between the ears K and K on the casing D. The lug cZ is cen- 7o trally apertured and is connected with a pipe M, extending laterally from the retort, and at its outer end connected to the valve N. This valve is preferably of the needle type and forms a connection between the pipe M and. the pipe B, leading from the oil-space of the tank A.

e is a hollow stem extending upward from and preferably formed integral with the retort L. At its upper end this stem is pro- 8o vived with a T-arm f, which forms the screwthreaded socket for the stem O of a needle- Valve. This Valve controls a jet-aperture g, formed in the stein e and directed laterally into a mixing-tube P. This mixing-tube is in 8 5 the form of an angle-fitting, which at one end is screwed or otherwise secured to a lug 7L, formed integral with the retort L. At the angle of the fitting is a downwardly-extending lug t', which is apertured for the passage 9o of the pipe M therethrough and forms a brace connection between said pipe and the :fitting P. In the space between the tting P and the hollow stem e is arranged a hood j, which is connected to a sleeve 7a, the latter surround- 9 5 ing an apertured tube Z and being provided with corresponding apertures, so as to constitute a valve for controlling ther air-inlet into the fitting P.

The fitting G is preferably formed integral Ioo with the casing of a plug-valve Q, which controls a lateral inlet into the pipe F. This valve-casing is connected by a pipe R with the tting P.

The parts being constructed as shown and described, the operation isvas follows: The liquid in the tank A being under pressure it will be forced through the pipe B to the valve N, which in the initial position of parts is closed. The air in the tank A above the liquid will be saturated with the vapor of the hydrocarbon oil, so as to form a combustible gas, which passes through the pipe C to the valve I. To start the generator, the valve I is first opened, which permits the vapor in the pipe O to pass through the jet-nozzle cc into the mixing-pipe F and from the latter into the chamber within the casing B belowr the perforated diaphragm J. The gas then passes through the apertures in said diaphragm and may be ignited to form a flame directly beneath the retort. Thus the generator may be started without the burning of any of the liquid hydrocarbon, and as the vapor passing through the jet-nozzle c is mixed with air entering through the hood II and apertures ct a blue iame is produced from the start. `This will do away with the objectionable deposit of soot, which is unavoidable where the liquid hydrocarbon is used for starting the burner. Then the flame has sufficiently heated the retort L, the valve N is opened to admit the liquid hydrocarbon through the pipe M into the retort, where it will be instantly vaporized and will pass upward through the hollow stem e. The valve O may then be opened to permit of the passage of a jet of Vapor into the fitting P,'where it will be mixed with air entering through the hoodj. The fitting P is connected with a service-pipe, S, so that the combined air and vapor will pass through said pipe to the point of combustion. A small portion of the vapor will, however, be drawn downward through the pipe R and pass the valve Q into the pipe F, and thus after the generator is started the valve I may be shnt ott.

The apparatus as above described forms an eicient generator,which may be easily started at any time, while the construction of parts is simple, so as to reduce the cost of manufacture.

What we claim as our invention is- 1. In a carbureter, the combination with a tank adapted to contain oil and air thereabove and in contact therewith under pressure, of a retort, a vapor-burner for heating said retort, a valve-controlled pipe connecting the liquid-space of said oil-tank with said retort, and a second valve-controlled pipe connecting the air-space of said oil-tank with said burner, whereby the Vapor-saturated air within said oil-tank may be burned to furnish the initial heat to said generator and also form the propelling force for feeding the oil.

2. In a carbureter, the rcombination with a tank adapted to contain oiland air thereabove and in contact therewith under pressure, of a retort, a Vapor-burner for heating said retort, a mixing-tube into which the vapor is directed from said retort and which is connected with the service-pipe, a valve-controlled pipe connecting the oil-space of said oil-tank with said retort, a second Valve-controlled pipe connecting the air-space of said oil-tank with-said vapor-burner and a pipe connecting said mixing-tube with said vaporburner, for the purpose described.

3. In a carbureter, the combination of a cylindrical burner-casing open at its upper end and having ears projectingupwardly from opposite sides thereof, a retort in the form of a hollow disk arranged between said ears above said burner, an oil-inlet pipe to said retort passing through an aperture in one of said ears,a valve-controlled vapor-outlet stem projecting upward from said retort, a mixingtube supported upon said retort in line with the Vapor-outlet and a depending apertured lug on said mixing-tube engaging with said oil-inlet pipe and forming a brace.

In testimony whereof we affix our signatures in presence of two witnesses.
